Natural Killer (NK) Cells Test

CD3- CD56+


Test Code: 505016
Specimen Type: Blood

Description:

Natural Killer (NK) Cells Test

This test measures the levels of Natural Killer Cells in the blood.  Natural Killer Cells (NK Cells) are a type of lymphocyte, or white blood cell, which play an important role in the body's immune system.  NK cells help to kill tumor cells or cells infected with a virus.  NK cells are identified and differentiated from other types of immune cells by certain antigens called CD proteins.  NK cells are CD56 positive and CD3 negative.

This test includes measurements for:

  • Percentage CD3-CD56+ NK
  • Absolute CD3-CD56+ NK
  • Absolute Lymphocyte Count

Measuring Natural Killer Cells can help to evaluate the function of a person's immune system.  It can also be useful in diagnosing or monitoring treatment to conditions such as leukemia, viral hepatitis, and HIV.  

Turnaround for this test is typically 2-4 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
